To azl whom it may concern:

Be it knownthat I, Cmznn E.Monns- -wo'n'rn, a citizen of the United States, re-

sidin at Los Angeles, in the'count of Los Ange es and State of California, we invented a new and useful Rectifier for Refrigerating ing is a spec cation.

This invention relates to means for dehydrating. the gas or vapor used in a r"e'-' 'frigeratng apparatus, operating on theammonia ibsorption princ ple. In such apparatus the vapor which passes off from the generator contains aconsiderable percentage of water and it is essential to economy and eflicie'ncy of the operation that this water should is removed from the'gas before it is condens ed.

The main object ofthe present invention is to'perforrn this dehydrating operation -in an eii'ective and satisfactory manner.

Other objects of the'invention will ap pear hereinafter.

The accompanying drawings illustrate an embodiment of my invention, and referring thereto: Figure 1 is a perspective view of the rectifier, showing also the connections thereof with the generator. Fig. 2- is a i transverse section of the rectifier. Fig. 3 3O is a longitudinal sectionthereofl The rectifier comprises the casing or -tanl 1 formed, for example, as ametal cylinder, and having an inner tube, preferably at the bottom 2 of its cylindrical'wall and intermediate the ends thereof, and having an outlet in the form of 'a pipe 3 which extendslongitudinally in the cylinder-and is provided with slits or perforations 4 in its bottom, said slits or perforations being dis-' tributed along the pipe so asto provide for the outflow of the gas from the tank.or casing 1 into ,the pipe from diiferent points alon the length of th tank. The interior of the tank or casing 1 is occupied with miner'al'wool, indicated at 5, which fills the space between the Walls of the casing l and the outlet pipe 3, so that the gas in the casing has to pass through this mineral ivool before it reaches the perforations 4: in the outlet pipe.

The above adapted to effect the final rectificati n or deh dration of the gas or vapor, and is 'pre erably'conn'ected with the still or gen- 'erator indicatedat 7, in Fig. 1, through 1nrfipparatus, of which the follow s ec ali m imeli ess, Patented Feb. is, was.

' .termediate or; preliminary dehydrgtion means, indicated at 9, the outlet pipes 10 for the generatorleadin into the settling tank 8 which is of. consi erable volume, so that the velocity of the gas passing therethrough is reduced andthe larger particles of en- The trained water are allowed to settle. co1l'9 leads from the tank 8 to the inlet tube of. there'ctifier'l, said coils being of'suficient, length and being exposed to a cooling vided for the coil 9 and rectifier 1. Foriexample, these parts may be immersed inv a cooling liquid, suppliedinany suitable mam ner, or by providing sufficient surface the atmospheric air surrounding this part may .be used forcool-ing the same. The generator ,7 may be ofanydesired form, consisting, for example, of cylinders, adapted to receive thebinary liquid consisting of the I refrigerating gas or vapor and liquid for absorbing the same. The burner or heater for heating the generator or still. is indicated at 12.

The rectifier above described is used in connection with refrigeration by meansof :any suitable refrigerating medium on the absorption system and the operation thereof will be described in connection with a systcm in which ammonia is used as a refrigerating medium and'water is .used as the absorbing liquid.

The operation is as follows: When the still orgenerator 7 is he .ted, the ammonia gas or vapor: passes through the outlet pipe 10 into 'thetank 8, wherein any. entrained Water particlesfisettle and drain back into the generator. The gas or vapor passes on from the tank 8 through the coil 9 and is cooled therein, resulting in condensation of most of the Water vapor, carried over with the gas or vapor of the refrigerating medium, such condensed Water drainingback into the tank Sand generator 7. The gas or vapor, when it reaches therectifying cas-- ing 1 is nearly at the temperature of condescribed rectifying meansis ,densatio n of the refrigerating medium or is surface of solid materiah .The cooling effect is brought into contact with an enormous of such surface and the entangling and filtering eifect of the fibers of the mineral 'wool serve to catch and hold the condensed moisture, so that the gas or vapor by the time it reaches the outlet perforations 4 is substantially dehydrated. The gas or vapor passing through the outlet 4 into the outer pipe 3 is delivered by pi e 3 to any suitable condensing means to e ect the next operation in the refrigerating cycle. The water which is collected or caught in the mineral Wool in casingl gradually drains back through the inlet tube. The refrigerating fluid 1s eventually returned to generator, lby pipe 11 extending into the generator cylinders.

What I claim is: A rectifier comprising a casin having an inlet, an outlet for said casing ormed as a pipe extendin within the casing, and havinga series 0 perforations along its length and mineral wool within said casing be tween the inletand said outlet pipe.

- In testimony whereof, I have hereunto set my hand at Los Angeles, California this 29th day of August, 1913;
